* fnmatch.h, fnmatch.c: New files.

	* ldlex.l: Remove unused definition of FILENAME.  Add definition
	of WILDCHAR.  In SCRIPT mode, accept any sequence of WILDCHAR as a
	NAME.
	* ldgram.y (file_NAME_list): Accept '*' and '?' specially.
	(input_section_spec): Accept '?' specially.
	(statement): Change exp to mustbe_exp in length and FILL cases.
	(section): Call ldlex_script before section statements, and call
	ldlex_popstate after them.
	* ldlang.c: Include "fnmatch.h".
	(wildcardp): New static function.
	(wild_section): Permit the section name to be a wildcard.
	(wild_file): New static function, broken out of wild.
	(wild): Call wild_file.  Permit the file name to be a wildcard.
	(open_input_bfds): Don't call lookup_name for a wildcard pattern.
	* Makefile.in: Rebuild dependencies.
 	(CFILES): Add fnmatch.c.
	(HFILES): Add fnmatch.h.
	(OFILES): Add fnmatch.o.
	* ld.texinfo: Document that file and section names can now be
	wildcard patterns.

	* ldlang.c (lang_place_orphans): Correct condition: place a common
	section if not relocateable or if common definitions are forced.
